Overview
Utah splits oversight of portable and mobile X-ray equipment across two separate state agencies, and both tracks matter if you're deploying equipment outside a fixed room. The Division of Waste Management and Radiation Control (DWMRC), part of the Department of Environmental Quality, regulates the equipment itself — registration, inspection, shielding, and technical operating standards. The Division of Occupational and Professional Licensing (DOPL), part of the Department of Commerce, licenses the people operating it. This guide focuses specifically on when and how portable equipment can be used under Utah's rules — not the full facility registration process.
Regulatory Framework
Utah's radiation control requirements are set out in the Utah Administrative Code, Title R313 (Environmental Quality, Radiation Control), administered by DWMRC. The rules most relevant to medical, dental, veterinary, and chiropractic X-ray equipment are R313-28 — Use of X-Rays in the Healing Arts (general/administrative requirements, diagnostic system standards, operator qualifications) — and R313-15 — Standards for Protection Against Radiation (dose limits, personnel monitoring, posting).
Operator licensure sits under a separate statute — Utah Code Title 58, Chapter 54 (the Radiologic Technologist Practice Act) — administered by DOPL, not DWMRC.
When Portable Equipment May Be Used
Utah's rules place a specific, meaningful limit on portable use itself. Under R313-28-31, "portable or mobile equipment shall be used only for examinations if it is impractical to transfer the patient to a stationary radiographic installation." In other words, portable use isn't a default option — it's meant for situations where bringing the patient to a fixed room genuinely isn't practical (a nursing home resident, a homebound patient, an urgent field situation), not as a general substitute for a properly shielded room. Keep this standard in mind when documenting why a given exam was done portably.
Equipment & Operating Requirements
Utah's general diagnostic X-ray requirements (R313-28-35) and portable-specific provisions (R313-28-53) set out several concrete technical standards:
- FDA certification. Equipment must be FDA-approved for use in the U.S. and certified under 21 CFR 1010.2 and 1010.3.
- Minimum source-to-skin distance. Mobile or portable radiographic systems must be equipped with a means to limit source-to-skin distance to 30 centimeters (about 12 inches) or greater.
- Warning label. Each unit must carry a label reading: "WARNING: This x-ray unit may be dangerous to patient and operator unless safe exposure factors and operating instructions are observed."
- Technique factor display. The technique factors to be used must be indicated before the exposure begins (except where automatic exposure control is used).
- Tube selection indication. If more than one tube can be energized from a single exposure switch, the selected tube must be clearly indicated before exposure.
- Mechanical stability. The tube housing must remain stable during exposure unless movement is a designed function of the system, and all positioning, locking, and centering devices must function as intended — worth a specific pre-use check on portable units that get moved and jostled between locations.
- Battery charge indicator. Battery-powered portable generators must visually indicate on the control panel that battery charge is adequate for proper operation before an exposure is attempted.
Structural Shielding and Distance
Because portable exposures often happen outside a shielded room, Utah's rules set specific protection standards for anyone nearby (R313-28-31):
| Who | Required Protection |
|---|---|
| Operators and other non-patients | Not less than 0.5 mm lead equivalent from the primary beam |
| Patients who cannot leave the room/area during exposure | Not less than 0.25 mm lead equivalent barrier, or positioned at least 2 meters from the equipment |
For patients who must be held in position for a portable exam, this means either a lead barrier or maintaining that two-meter separation — not simply stepping back a pace or two.
Who Can Operate Portable Equipment
Operators of diagnostic X-ray systems in Utah must be licensed to practice under Utah Code Title 58, Chapter 54, and the facility (the "registrant" in Utah's terminology) is responsible for confirming that the operator has been instructed in both the proper choice of technique factors and the safe, effective operation of the specific equipment being used (R313-28-350).
DOPL currently licenses three relevant credential categories:
- Radiologic Technologist — requires current ARRT or NMTCB certification.
- Radiology Practical Technician (RPT) — requires a passing score on the ARRT Limited Scope Examination (core module plus at least one additional anatomical section) or the ARRT Bone Densitometry Equipment Operators exam.
- Radiologist Assistant — requires a bachelor's degree plus ARRT Radiologist Assistant or CBRPA Radiology Practitioner Assistant certification.
The application-processing fee is $70, non-refundable, for any of the three categories. Utah also offers licensure by endorsement for applicants holding an equivalent out-of-state license in good standing with at least one year of practice experience.
Notably, Utah's diagnostic X-ray rules place safety responsibility on the facility ("registrant") rather than requiring a separately designated Radiation Safety Officer the way some other states do — confirm your facility's internal safety-program structure satisfies R313-28-31's registrant-responsibility requirements even though no specific RSO title is mandated in this part of the rule.
Personnel Monitoring & Dose Limits
Utah's occupational dose limits (R313-15-201) and monitoring triggers (R313-15-502) are:
| Category | Limit |
|---|---|
| Annual occupational total effective dose equivalent (adults) | 5 rem (0.05 Sv) |
| Annual dose to lens of the eye | 15 rem (0.15 Sv) |
| Annual dose to skin, extremities, or any single organ | 50 rem (0.50 Sv) |
| Monitoring required when likely to exceed | 10% of the applicable annual limit (500 mrem / 0.5 rem for whole-body TEDE) |
| Minors — monitoring trigger | 1 mSv (0.1 rem) annual deep dose equivalent |
| Declared pregnant workers — monitoring trigger | 1 mSv (0.1 rem) during the declared pregnancy |
Individual dosimetry is also required, regardless of estimated dose, for anyone who enters a high or very high radiation area, and for staff who operate medical fluoroscopic equipment. If your portable/mobile program includes fluoroscopy or frequent high-workload use, plan on dosimetry for that staff as a baseline requirement rather than something triggered only by a dose estimate.
Required Signage
This is a point where Utah differs from many states: under R313-15-903, a room or area is not required to be posted with a caution sign solely because of the presence of radiation machines used for diagnosis in the healing arts. Diagnostic medical, dental, veterinary, podiatric, and chiropractic X-ray rooms are specifically exempted from the general caution-sign posting requirement that otherwise applies under R313-15-902. This exemption applies to fixed rooms and, by extension, to portable use in the healing arts — but it's specific to diagnostic use, so confirm applicability if your equipment is also used for anything outside strict diagnostic purposes.
Registration & Inspection
Every X-ray tube attached to a control unit anywhere in Utah must be registered annually with DWMRC — this applies to portable and mobile units the same as fixed installations.
Registration fee: $55 per tube, per year (paid at initial registration, then billed annually).
Change notification: DWMRC must be notified within 14 days of acquiring, transferring, or disposing of a registered unit.
Registration numbers: the facility receives a permanent registration number, while each machine separately receives a Utah Machine ID number that stays with the unit even if it moves between facilities — worth tracking closely if your portable equipment serves multiple locations or changes hands.
Inspection frequency and fees vary significantly by facility type — this is one of the more distinctive parts of Utah's program:
| Facility/Use Type | Inspection Interval | Inspection Fee (per tube) |
|---|---|---|
| Hospitals | 1 year | $140.00 |
| Medical — fluoroscopic/CT | 1 year | $140.00 |
| Radiation therapy | 1 year | $140.00 |
| Industrial (high radiation) | 1 year | $140.00 |
| Veterinary — fluoroscopic/CT | 1 year | $100.00 |
| Chiropractors | 2 years | $140.00 |
| Medical — general radiographic | 2 years | $140.00 |
| Podiatrists | 5 years | $100.00 |
| Veterinarians (standard) | 5 years | $100.00 |
| Dentists | 5 years | $65.00 first tube, $30.00 each additional |
| Independent qualified-expert inspection | — | $50.00 |
Facilities using portable equipment for mobile/urgent-care-style services generally fall closest to the "medical — general radiographic" category unless fluoroscopy is involved, but confirm classification with DWMRC directly since a facility's actual inspection category depends on its registered use, not just its equipment type.
Quick-Reference Checklist
- Confirm portable use is justified — it's impractical, not just convenient, to transfer the patient to a stationary room
- Register every tube with DWMRC annually ($55/tube) and notify the Division within 14 days of any acquisition, transfer, or disposal
- Confirm the unit limits source-to-skin distance to 30 cm or more
- Check that the warning label, technique-factor display, and (for battery units) charge indicator are present and functioning
- Provide 0.5 mm lead equivalent protection for operators/non-patients from the primary beam
- For patients who must remain in the area, use a 0.25 mm lead barrier or maintain at least 2 meters of distance
- Confirm the operator holds an active DOPL license (Radiologic Technologist, RPT, or Radiologist Assistant) appropriate to the exam
- Issue personnel dosimetry to anyone likely to exceed 10% of the annual dose limit, and to any fluoroscopy operator regardless of estimated dose
- Diagnostic-use rooms are exempt from caution-sign posting — don't assume a posting violation where none applies, but confirm if equipment serves any non-diagnostic use
- Know your facility's inspection interval (1, 2, or 5 years depending on use) and keep records current between visits
